Very easy to install and looks great. Sat out in an overnight rain and no water at all inside. There are several good YouTube tutorials on installing.

I had one of these on my last truck, love it. I had to spend a couple more minutes adjusting it on my new truck because of the automatic tail gate. Once adjusted properly it fits great. No gaps, cracks or anything, and the automatic tailgate works like a charm.

The cover came with a broken corner piece but was replaced through AAG customer service so that was nice. Other problems with the manufacturing process looked like they just weren’t diligent with putting it together. All the holes had to be deburred before I could insert the bolts and two of the rubber connectors between the panels weren’t inserted into the slots. I was disappointed to see this thinking that someone just didn’t care but overall the final install is very nice. I was able to use my bacbox from my previous truck so that was good.

For my application it is perfect. I have tried all the different foldings. Even against the back glass and no rattling or noise.

Cover arrived earlier than expected. Out of the box and easily installed in less than 30 minutes. Like the look and easy function of the cover. Makes my new gmc look even better. If you want a quality bed cover the BakFlip is worth a look.

Very nice tonneau cover. Most of the time was spent adjusting the cover--the rails should have been installed closer to the rear of the bed, we first mounted them toward the front of the bed. Once centered, the cover fit perfectly. Very nice quality.

I purchased the BAK MX4 and installed it myself. Install was straightforward and I am very pleased with the quality, fit and finish if this cover. The strap female kit was missing two screws; I left a message with BAK CS and a entire strap kit was shipped to my home at no charge (thank you Christie). Very well made cover, easy installation and great CS.

This cover was here quicker than I expected. It took me about 90 minutes to install and that included a Bak Box. The price was also better than I found anywhere.

Seems like good solid construction. Fit is fine. I wish they would have a track with this cover so I could get a rack that would be compatible and install and remove easily. Also added the BakBox. Got a good price on the pair at AAG.

I love the look and ease of opening and closing. Seems to be built pretty solid. I wish the locks that hold it were metal but they seem to be a plastic but still strong. I think if someone really wanted they could easily open it with a pry bar. That being said I don't plan on leaving valuables in the bed for long periods of time. I do like the ability to carry cargo in the bed without having to worry about anything flying out.

Easy to install, looks great on the vehicle. My only complaint is it was scratched and had minor damage that I had to fix before install. This was not the distributors fault as there was damage to the packaging. Overall very happy with the purchase and AAG.

Easy to install, under 30 minutes. You do need a second person to assist when putting cover on. Looks great and very sturdy. Automatic tailgate still works with bedcover locked. Appears to seal tightly against water. Washed truck after install and absolutely no water in the truck bed. Only negative comment. The directions left out what to do with second rubber washer. I put on top to seal the bolt hole coming through. Would be good to have pictures. I would purchase again and recommend to anyone looking for a great quality cover.

Everything was packaged very well and instructions were easy to follow and installation only took 45 minutes. The only thing that was a little bit of a problem was the stick on bumpers on the very front outside part of the cover were not stuck on very tightly. I may need to get new ones.

The overall product is great. I think there are areas that could improve such as the corner covers are flimsy and plastic. The rear bar going across the tailgate could look a little more professional as the end is just cut off with no Paint just aluminum showing. Went to the car wash after install and no water inside.

Even though I have a slight disability with my hands, I was able to install the cover by myself in just a little over an hour. Using ratchet clamps to align and hold the rails helped a lot. It would be great if the t-bolts had some sort of grip to prevent them from spinning while tightening them down. This is the 2nd Bakflip I’ve installed on trucks I’ve owned and they are a good quality product. They finish off the truck nicely and help secure cargo.

The cover was easy to install and it looks great. The part that took me the longest was making sure it was center so it closed easily.

I love this cover but if I were making it I would do the following. 1 - Use a thicker gauge aluminum for both the top and bottom since it is a skin to Styrofoam. 2 - Use Blue Construction foam board like what is used on home insulation. Stronger closed cell board. 3 - Make the cover about 3/4" to 1" longer so that it seals better on both the front and rear of the bed. 4 - Use longer bolts on the front mount so that they reach easier.

This is my second BakFlip cover. I bought this for a 2019 Silverado crew cab with short bed. Everything arrived in good shape. I viewed the installation video as a refresher and it is extremely helpful. The mx-4 is considerably lighter than my old G1 which I view as a big plus. I also love the buckle system to allow exposing most of the bed while not blocking the view out back window of truck - another nice improvement. I had 2 issues in the installation that caused some delay. I found an adhesive foam under the piece next to cab where the flat bolt runs through to tighten down. No pre punched hole but I left it after punching hole as I believe it was intended to be used and figured it would cut down on any potential metal on metal rattle. Biggest issue was that my automatic tailgate would not drop after tightening everything. Called Autoaccessoriesgarage who gave me a direct number for BAK Industries. Moving the cover forward more than the 1/4 inch clearance in instructions worked and all is well! Added notes in instructions would have been helpful since I am sure that I am not the first to experience this. This is a great, watertight, durable cover!
